by Nathanaël Blanchet 26 Nov '18

26 Nov '18

Hi, What are the best pratices about vm snapshots? Is there a maximum number of snapshots per vm? Has a high number of present snapshot an impact on the vm performance? ... on how long the snapshot is completed? -- Nathanaël Blanchet Supervision réseau Pôle Infrastrutures Informatiques 227 avenue Professeur-Jean-Louis-Viala 34193 MONTPELLIER CEDEX 5 Tél. 33 (0)4 67 54 84 55 Fax 33 (0)4 67 54 84 14 blanchet(a)abes.fr

NFS storage and importation
by AG 26 Nov '18

26 Nov '18

Hello, Our cluster use NFS storage (on each node as data, and on a NAS for export) We currently have a huge problem on our cluster, and export VM as OVA takes lot's of time. I checked on the NFS storage, and it looks like there's files who might be OVA in the images directory, and OVF files in the the master/vms Can someone tell me if, when i install a new engine, there's a way to get this VMs back inside the new engine (like the import tools by example) Thank you a lot for your answers, Regards, Alexis ps : it should be said in the documentation to NEVER use backup of an engine when he is in a NFS storage domain on a node. It looks like it's working, but all the data are unsynch with reality.

Hosted-engine restore to another data center
by kannis＠sitespect.com 23 Nov '18

23 Nov '18

Hello all, I'm trying to work out if it's possible to backup and restore a hosted-engine from one data center to a new hosted-engine in another data center. I am working on setting up oVirt across physical co-locations sites without shared storage between them and being able to restore a hosted-engine backup in another data center would be useful if the co-lo where the hosted-engine normally runs were to go down. Best, Kevin

ansible ovirt_vm_facts and custom_compatibility_version attributes
by Nathanaël Blanchet 23 Nov '18

23 Nov '18

I'd like to manipulate with ovirt_vm_fact ansible module some vm attributes in the API lik_e _custom_compatibility_version. <https://infra.v100.abes.fr/ovirt-engine/apidoc/#/types/vm_base/attributes/c…> Right from the APi description, it is available from the VmBase struct, but I can't find it in the return ovirt_vm_facts value, neither with nested attributes. How should I do ? -- Nathanaël Blanchet Supervision réseau Pôle Infrastrutures Informatiques 227 avenue Professeur-Jean-Louis-Viala 34193 MONTPELLIER CEDEX 5 Tél. 33 (0)4 67 54 84 55 Fax 33 (0)4 67 54 84 14 blanchet(a)abes.fr

RDP as default console for Windows VM
by Anantha Raghava 23 Nov '18

23 Nov '18

Hi, In the past, we could set RDP as default console for Windows VM. VMs used to reboot once we set RDP under console options & become default for all users. In the new versions I am unable to achieve the same result. Is there a way to set RDP as default Console for Windows VM? -- Thanks & Regards, Anantha Raghava Do not print this e-mail unless required.

Ovirt VNC Server
by Hari Prasanth Loganathan 23 Nov '18

23 Nov '18

Hi Team, I have a VM for which I applied the console configuration as VNC. Now I have installed a tool Guacamole to connect to this VM from outside. As per Guacamole, It expects the following parameter to connect to the VM using VNC, <connection name="*Unique Name*"> <protocol>vnc</protocol> <param name="hostname">172.1.1.1</param> <param name="port">*5901*</param> </connection> I understand that the IP Address is VM's IP address but what is the port I need to use for connecting to the VM? What is the VNC server port in ovirt? Anyhelp is appreciated.

Can i use l2-cache-size parameter for qcow2 images with Ovirt?
by zimmer＠bbaw.de 23 Nov '18

23 Nov '18

Hi, i'm new to Ovirt. Can i create qcow2 images with l2-cache-size parameter? Qemu supports it, see http://blogs.igalia.com/berto/2015/12/17/improving-disk-io-performance-in-q… But i'm not sure if the Ovirt frontend can handle it? thanks, Kai
